Frequent exercise can lower the risk of stroke
Wednesday, March 12, 2014
Frequent exercise can lower the risk of stroke - Frequent exercise to sweat is known to lower the risk of stroke in middle-aged to elderly, according to recent research. Compared to people who never exercise, people who work up a sweat at lower risk.
"A healthy diet, a healthy weight, exercising regularly and avoiding bad habits like smoking and drinking alcohol can reduce the risk of stroke by 80 percent. Meanwhile, the most important aspect of the exercise is to be done," said study author Michelle McDonnell, as reported by U.S. News.
According to McDonnell, exercise can reduce the risk of stroke by boosting blood vessel health. Indirectly it also lowers the risk of high blood pressure and obesity.
This study was conducted with 27,000 people following the Americans starting in 2003 to 2007. Participants were aged 45 years or older at the start of the study and had no history of stroke never experienced before. During this study several cases of stroke occurred in participants.
Approximately 3.1 percent of those who diligently exercise group experienced a stroke, compared with 3.3 percent of people who only exercise one to three times a week, and 3.6 percent in the group that did not exercise.
After making observations and statistics by eliminating other factors, researchers found that a group of people who exercise often have a 20 percent lower risk of stroke than those who never exercise.

Frequent heartburn may predict cancers of the throat and vocal cord
Saturday, March 8, 2014
Frequent heartburn was positively associated with cancers of the throat and vocal cord among nonsmokers and nondrinkers, and the use of antacids, but not prescription medications, had a protective effect, according to data published in Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research.
"Previous studies examining gastric lux and cancers of the head and neck have generated mixed results," said Scott M. Langevin, Ph.D., postdoctoral research fellow at Brown University in Providence, R.I. "Most of those studies had either few numbers of cases or they were not adjusted for confounding factors. Ours is a large, population-based study with robust parameters that strongly suggests gastric lux, which causes frequent heartburn, is an independent risk factor for cancers of the pharynx (throat) and larynx (vocal cord)."
Langevin and his colleagues identified 631 patients from a large group of individuals enrolled in a population-based, case-control study in the greater Boston area. Of the 631 participants, 468 had throat cancer and 163 had cancers of the vocal cord. An additional 1,234 individuals matched for age and gender with no prior history of cancer were recruited using town records to serve as controls for the study.
All participants completed a questionnaire on their history of heartburn, smoking and drinking habits, family history of cancer and sociodemographic information. Because some head and neck cancers are caused by infection with human papillomavirus 16 (HPV 16), the researchers tested for the presence of antigens to HPV 16 viral proteins in the blood of all participants.
Langevin and his colleagues found that among participants who were neither heavy smokers nor heavy drinkers, a history of frequent heartburn was linked to a 78 percent increased risk for cancers of the throat and vocal cord. They also found that among those who had frequent heartburn, taking antacids, but not prescription medications or home remedies, had a protective effect, with a 41 percent reduced risk for cancers of the throat and vocal cord. The protective effect of antacids was consistent, irrespective of the participants smoking or drinking status, HPV 16 status or tumor site.
"Additional studies are needed to validate the chemopreventive effects of antacids among patients with frequent heartburn," said Langevin. "The identification of gastric lux as a risk factor for throat and vocal cord cancers, however, may have implications in terms of risk stratification and identification of high-risk patients."
